Abstract
The present invention provides a medical robot which is hygienic and capable of precisely transferring a catheter, a driving device mounted on the medical robot, and a roller module mounted on the driving device. The roller module includes: a driving unit; and a roller unit rotated about the vertical axis by the driving unit, wherein the roller unit includes at least one roller and at least one shaft independently coupled to the at least one roller of the roller unit and rotated by the driving unit, wherein at least one groove is formed on the at least one roller of the roller unit and at least a part of the at least one shaft of the roller unit is disposed on the at least one groove.
Core Innovation
A driving device for a medical robot is provided. The driving device includes a base module and a first roller module and a second roller module, where the base module controls a spacing between the first roller module and the second roller module.
At least one of the first roller module or the second roller module includes a driving unit and a roller unit that is rotated by the driving unit while a rotation axis of the roller unit is a vertical direction. The roller unit includes at least one roller and at least one shaft independently coupled to the at least one roller, and at least a portion of the at least one shaft is independently received in a hole or groove defined in the at least one roller.
A medical robot is disclosed that comprises a first driving device, a second driving device, and a third driving device to transport a guide catheter, a guide wire, and a balloon catheter, respectively. At least one of these driving devices includes the base module with the first roller module and the second roller module, and at least one of the guide catheter, the guide wire, and the balloon catheter is disposed and clamped between the first roller module and the second roller module and is transferred via rotation of the roller unit of the first roller module and the roller unit of the second roller module.
Claims Coverage
The document includes two independent claims that cover five inventive features: spacing control between first and second roller modules, vertical-axis roller rotation with independently received shafts, vertical-direction movement to rotate a clamped surgical tool, a medical robot with three driving devices for transport of a guide catheter, guide wire, and balloon catheter, and coordinated clamping and transfer by parallel, oppositely rotating roller units.
Base-module spacing control between first and second roller modules
A base module controls spacing between a first roller module and a second roller module.
Vertical-axis roller rotation using independently received shafts
A roller unit is rotated by a driving unit while a rotation axis of the roller unit is a vertical direction, and at least one shaft independently coupled to at least one roller is independently received in a hole or groove of the roller.
Vertical-direction movement to rotate a clamped surgical tool
At least one of the roller units of the first roller module and the second roller module is configured to move in the vertical direction by the driving unit to rotate a surgical tool clamped between the roller units.
Medical robot with three driving devices for transporting catheter, guide wire, and balloon catheter
A medical robot includes a first driving device, a second driving device, and a third driving device to transport a guide catheter, a guide wire, and a balloon catheter, respectively.
Clamping and transfer via coordinated roller-unit rotation
At least one of the guide catheter, the guide wire, and the balloon catheter is disposed and clamped between the first roller module and the second roller module and is transferred via rotation of the roller unit of the first roller module and the roller unit of the second roller module, with parallel rotation axes and opposite rotation directions.
Across the independent claims, inventive coverage centers on base-module-controlled spacing between first and second roller modules, roller units having a vertical rotation axis with independently received shafts in roller hole or grooves, and coordinated clamping and transfer of surgical tools and medical catheters through parallel roller axes and opposite rotation directions.
Stated Advantages
Not explicitly described in patent.
Documented Applications
A medical robot that transports and clamps a guide catheter, a guide wire, and a balloon catheter, and transfers them via rotation of roller units.
